Cochise can sometimes be rather pessimistic. However, he is still loyal to the pack that gave him a home when no other would. Due to his sarcastic tone, he doesn't get along too well with others. So when Kachina assigned him first to be a pup sitter, she realized her mistake when her pups came to her whining of his condescending tone.
As such, she rectified her mistake and assigned him to scouting duties. There have been no further complaints about his behavior since. During the puppy boom, he was promoted to a hunter on Johonaa'ei's team and has been happy with his position since.
